従来のＬＥＤチューブは、ＬＥＤライトバー及びＬＥＤライトバーを囲むランプカバーを備える。しかし、従来のＬＥＤチューブは、面光源であるため光収束性能が悪い。従って、高い光強度分布を必要とする場合、照明要求を満たすことができない。   A conventional LED tube includes an LED light bar and a lamp cover surrounding the LED light bar. However, since the conventional LED tube is a surface light source, its light convergence performance is poor. Therefore, when a high light intensity distribution is required, the illumination requirement cannot be satisfied.

The lamp cover is made of a light guide material. A semi-cylindrical shape, having an outer surface and an inner surface facing the outer surface, and the thickness of the lamp cover in the radial cross section gradually decreases from the center toward both sides, and a plurality of light emitting elements The light emitted from the lamp is emitted to the outside through the lamp cover.

従来の技術と比べ、本発明に係るランプカバー及び照明装置において、半径方向の断面におけるランプカバーの厚さは、中央部から両側に向けて徐々に薄くなるため、ランプカバーを通過した光は、ランプカバーの中央部に向かって収束される。これにより、照明装置の光収束性能を向上させ、照明装置の光照射野の中央部の明るさを向上させることができる。   Compared with the prior art, in the lamp cover and the lighting device according to the present invention, the thickness of the lamp cover in the radial cross section gradually decreases from the center toward both sides, so the light that has passed through the lamp cover is It converges toward the center of the lamp cover.

The heat dissipation device 30 includes a base 31 and a fin unit 32 that protrudes downward from the bottom surface of the base 31. The fin unit 32 includes a plurality of fins 321 extending along the longitudinal direction of the base 31 and installed in parallel with each other. Engagement portions 33 are formed on two sides in the longitudinal direction of the base 31, and the heat dissipation device 30 is engaged with the engagement portion 13 of the lamp cover 10 with the lamp cover 10. Fixed to. In the present embodiment, the locking portion 33 is a groove formed on two sides of the base 31 and having an opening in a direction away from the base 31, and the groove is an engaging portion of the lamp cover 10. Used to house 13 The base 31 includes an upper surface 311 and a lower surface 312 facing the upper surface 311, and the fin unit 32 is installed on the lower surface 312 of the base 31. The height of the plurality of fins 321 gradually decreases from the center of the base 31 toward both sides of the base 31. Thereby, the convection of air can be strengthened.

また、ＬＥＤライトバー２０の支持板２１と放熱装置３０のベース３１の上表面３１１との間に、高い熱伝導率を有するシリカゲル層を設置しても良い。該シリカゲル層は、ＬＥＤライトバー２０の支持板２１と放熱装置３０のベース３１とに緊密に連接され、これにより、ＬＥＤライトバー２０の発光素子２２によって発生した熱を、放熱装置３０に素早く伝達することができ、放熱効率を向上させることができる。   Further, a silica gel layer having a high thermal conductivity may be installed between the support plate 21 of the LED light bar 20 and the upper surface 311 of the base 31 of the heat dissipation device 30. The silica gel layer is closely connected to the support plate 21 of the LED light bar 20 and the base 31 of the heat radiating device 30, thereby quickly transferring the heat generated by the light emitting element 22 of the LED light bar 20 to the heat radiating device 30.

Thereafter, the light is emitted from the lamp cover 10 to the outside. Since the thickness of the lamp cover 10 in the radial cross section gradually decreases from the center toward both sides, the light that has passed through the lamp cover 10 is converged toward the center of the lamp cover 10. Thereby, the light convergence performance of the illuminating device 1 can be improved, and the brightness of the center part of the light irradiation field of the illuminating device 1 can be improved. The lighting device 1 according to the present invention can improve the brightness of a predetermined area without increasing the number of light emitting elements 22.
